KNIFE-SHARPEN ER.

SPECIFICATION forming part of Letters Patent No. 590,624, datedSeptember 28, 1897.

l Application filed May 10, 1897.

T0 all whom it may concern.'

Be it known that I, JOSEPH PAQUET, a citizen of the United States,residing at Poughkeepsie, in the county of Dutchess and State of NewYork, have invented a 'new and useful Knife-Sharpener, of which thefollowing is a specification.

This invention relates to knife -sharpeners of that class in which theedge of the knife is drawn between the crossing edges of tempered-steelblades; and the object of the invention is to provide a simple landefficient device of this character which maybe manufactured and sold ata very low cost.

The invention consists of the several details of construction,combination, and arrangement of parts, as will be hereinafter fullydescribed, and particularly pointed out in the claims.

In the drawings, Figure l is a perspective view of the knife-Sharpener,the handle being shown in section. Fig. 2 is a perspective View of oneof the blades detached. Fig. 3

is a transverse section through the rear plate portions of the bladesand the shank.

Similar reference-numerals indicate similar parts-in the severalfigures.

1 indicates the sharpening-blades, each of which is provided at its rearend with an enlarged plate portion 2, which is integral with the blade.Each blade tapers toward its front end and each is beveled on one side,asindicated at 3, in order to form a knife-edge; The knife-edge of eachblade extends at an obtuse angle to the central longitudinal line of itsplate 2. The respective blades are beveled on opposite sides, and whenthe plates 2 are secured together with the flat faces of the bladesopposing each other the knifeedges will diverge toward the front end ofthe Sharpener and forni a V-shaped opening et between them for theinsertion of the knife to be sharpened, and when the knife-to besharpened is drawn through this opening with its edge in the apex of theopening a sharp edge will be formed on the knife bythe crosse ing edgesof the blades l, which will cut or shave a slight sliver from each sideof the blade of the knife being sharpened.

Each of the plate .portions 2 is provided with a groove 5 on its innerface, and whenl handle ll to the Sharpener.

Serial No. 685,912. (No model.)

the two plates are in their proper relative positions these grooves willregister and form a socket for the endof the shank 6. One

of the plates' is provided with a series of 55 threaded openings 7,- andthe other plate 2 is provided with a series of openings 8, adapted toregister with the openings 7 when the plates are in their properposition. The openings 8 are countersunk, as indicated at 9, for 6o thereception of the heads of the screws 10, bymeans of which the two platesare firmly secured together. It is obvious that when the plates 2 areclamped together by means of screws l0 the blades l will be securelyheld65 against movement relatively to each other, and at the same time theshank 6 will be firmly clamped between the two plates and thereby afforda secure attachment for the to be understood that the blades 1 will beof tempered steel and that the handle 1l may be made of any suitablematerial at the option of the manufacturer.

It will be understood that changes in the form, proportion, and minordetails of construction may be resorted to withoutdeparting from thespirit or sacriiicing any of th advantages of this invention.

Having thus described the invention, what 8o I claim is- 1. Aknife-Sharpener consisting of two tapering blades, each of which isbeveled on one side to form a knife-edge, and each of which is providedat its rear end with an en- 8 5 larged plate. portion integral therewithand from the central longitudinal line of which the knife-edge of theblade extends at an obtuse angle, and means to secure the plate portionsfirmly together with the flat side of 9c the blades op posing eachother, and with their knife-edges diverging toward the front end of theSharpener, substantially as described.

2. A knife- Sharpener consisting of two blades, the knife-edges of whichcross each other, and each blade having an integral plate portion at itsrear end, each of said plate portions having a groove in its inner face,which grooves are adapted to register to form a shank-receiving socket,and one of said roo plate portions having a series of threaded openingsand the other a similar series of It is of course 7o y counters unkopenings which register with the said threaded openin gs, screws securedin said openings to clamp the plate portions together` and a shankclamped in said socket, substantially as described.

3. A knife-sharpener consisting of two tapering blades each. of which isbeveled on one side to form a knife-edge, and each of which is providedat its rear end with an enlarged plate portion integral therewith, andfrom the central longitudinal line of which the knife-edge of the bladeextends at an ob tuse angle, each plate portion having a grooveextending centrally and longitudinally thereof on its inner face, saidgrooves, when registered, forming a shank'- receiving socket, and meansto secure the plate portions iirmly together with the flat side of theblades opposing each other and with the shank clamped in its socket,substantially as described.

4. A knife- Sharpener consisting of two blades the knife-edges of whichcross each other each blade having an integral plate portion at its rearend7 cach of said plate portions having a groove in its inner face,which grooves are adapted to register to form a shank-receiving socket,and means to clamp lthe plate portions together with the shank betweenthem, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aiixedmy signature in the presence of two witnesses.
